Turning my Zone 5 attic into conditioned space
So have been scouring for iso to do my basement walls and needed only 40 sheets, but Ive come across a guy who has 100 sheets and needs to get rid of them all at a crazy price.
So my question is can I use this 3′ iso on the underside of my rafters to bring my attic into a conditioned space.
The attic insulation is already at R60 (R38 batts and the rest blown in cellulose) but I thought if I have all this left over Iso I may as well use it in the roof and give my central air a break.
It has soffets and a roof ridge vent so my plan was to run the iso from where the rafters meet the attic floor up to say 6ins from the roof vent so the sheathing can breath, and do the ends up to the ridge.
Does that sound right I will tape all seams as I go but have I missed anything?
Education is always appreciated
